Combine the powers of StringUtils.repeat()
, StringUtils.center(
)
, and StringUtils.join( )
to create a textual header. The following example demonstrates the use
of these three methods to create a header:
public String createHeader( String title ) { int width = 30; // Construct heading using StringUtils: repeat( ), center( ), and join( ) String stars = StringUtils.repeat( "*", width); String centered = StringUtils.center( title, width, "*" ); String heading = StringUtils.join(new Object[]{stars, centered, stars}, "\n"); return heading; }
Here's the output of createHeader("TEST")
:
****************************** ************ TEST ************ ******************************
In the example, StringUtils.repeat(
)
creates the top and bottom rows with StringUtils.repeat("*", 30)
, creating a string
with 30 consecutive *
characters.
Calling StringUtils.center(title, width,
"*")
creates a middle line with the header title centered and
surrounded by *
characters. StringUtils.join()
joins the lines together
with the newline characters, and out pops a header.
